SPINDLE AND MEANS FOR SUPPORTING THE SAME.

SPECIFICATION formingpart of Letters Patent. No. 244,712, dated July 19, 1881. Application filed September 27, 1880. '(No model.)

To all whom it may concern Be it known that I, CH RLES H. CHAPMAN, of Shirley, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Spindles and Means for Supporting the Same, of which the following is a specification.

The invention consists in a standard for a shell-spindle fitted loosely and adapted to vibrate in its step or support, so that when the spindle is rotated the standard and spindle will be centered or held steadily in a vertical position by centripetal force, all of which I will now proceed to describe and claim.

The accompanying drawing, forming a part of this specification represents a vertical central section of a spindle having a loose step.

I have found in a shell-spindle supported by a standard,that if the standard is allowed to have some lateral play in its base or support the spindle will run more steadily than when the Standard is rigid.

I have shown a spindle having a standard, S, which is inserted in a base, T, having a socket of sufficient size to receive the standard and permit it to play laterally.

To secure the standard in the base so that it will not rotate with the spindle nor be pulled out when the bobbin is dotted I drill a hole, U, in the standard, insert a pin, V, in the hole, and then force the standard down into its base, the pin being of such length that its ends will bind tightly against the interior of the socket and prevent the Withdrawal of the standard. I The hole U is of such size that it will permit 5 the lateral play of the standard.

When thev spindle is rotated on the standard the centripetal force centers it and keeps it steadily in a vertical position, the principle being the'same as that of the well-known toy 40 known as the top. I

0 represents the live spindle, having a tapered whirl, D, and a pin, P, on the rail, to prevent the slipping off of the band from the whirl.

What I claim is 1. The combination of a spindle, 0, its standard S, and a socketed base, T, to receive said standard, the said standard being of considerably less diameter than the socket, so as to fit lodsely and vibrate therein, whereby as the Spindle is rotated the standard and spindle will be centered or held steadily in a vertical position, substantiallyas shown and described.

' 2. The spindle, a standard therefor, and a socketed base in which said standard is loosely fitted and adapted to vibrate, in combination with a pivot-pin, substantially as shown and described.

In testimony whereofv I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES H. CHAPMAN.
